I would be inclined to give the girl a break - I mean there have been so few occasions where she has been seen in public with Marat in the last decade that they have been 'together' (excluding Marat's affairs with Ekaterina and Nastya of course) you can hardly 'blame' her for whooping it up on Party night can you...what I find more interesting is Marat's body language in all the shots in which we can see them together...she is an expensive looking accessory.
